[Dovecot] Time zone problems with dovecot-1.0-stable (20050705 nightly snapshot)

[Jon Roma]

Timo:

Was there any more documentation you needed from me on the time zone
issue that we had an email exchange about a couple weeks ago?

It looks like you had a fix in mind, but drop me a note either on or off
list if I can help with the question of AIX environment variables or
anything else related.

Regards and thanks.
